It's too late for any of this. Nostr is ossified, it's past the days where talking about changing this or that spec is a realistic conversation. There is no realistic mechanism for any such change to propagate. You can tinker in Damus, but there ain't no big "spec" stuff happening no more. About two years ago was the cut off.

Where nostr 1.0 is at now, that's pretty much it for the rest of its life, take it or leave it.
